Скачать или смотреть Frontend Performance Practices at GitLab: From Core Web Vitals to Practical Fixes

(Session by Jacques Erasmus, Create:Source Code)

Learn how GitLab engineers think about frontend performance — from the evolution of “what fast means” on the web, to today’s Core Web Vitals, practical tooling, and workflows you can use to diagnose and fix performance issues.

In this session we cover:

Why performance matters for GitLab engineers
How “fast” evolved: from static pages → SPAs → seamless apps
Core Web Vitals (LCP, INP, CLS) and supporting metrics like TBT
Common causes of poor performance (with GitLab-specific examples)
Tooling and troubleshooting workflow (Identify → Fix)
Using GDK and the User Timing API to measure locally
Practical fixes and best practices you can apply right away
